Each journal is assigned to one of 22 research
fields. In ESI, a journal can be assigned to only one field. Journals such
as Science and Nature are categorized as multidisciplinary
since they publish research in many different fields. As a result, papers
published in these multidisciplinary journals are assigned to a field based on
the representation of the cited journals. For example, if the majority of
citations to a paper published in Science come from neuroscience
journals and the majority of cited references in the paper are to neuroscience
journals, the paper is then categorized as neuroscience.
